Can I substitute baking soda for baking powder in a recipe?

So I’m looking at a recipe that calls for both baking soda and baking powder. I am currently out of baking soda and I read that I can substitute with baking powder, but since the recipe already has baking powder in it; my question then is: can I substitute baking soda for baking powder even though the recipe already calls for baking powder as an ingredient?

Not my favorite sub, but you can substitute at a rate of 3 powder/ 1 soda. The baking soda in the recipe is presumably offset by acid in the recipe, and this substitution will change the balance a bit, but usually not seriously.

Okay thank you! Just wondering because it sucked that I was baking cookies and realized I didn’t have baking soda 😤
